As 3PP contests become more relevant, a need arises for analysis tools.

This page lets you enter certain preference-flow assumptions and get a graph back.

You can mouse over the dots to get a tool-tip with details of 3PPs and estimated winner and margin, based on the assumed preference flows.

Note that form input is in decimals: 80% becomes 0.8, 1% becomes 0.01, and so on.

This graphing tool was created at the instigation of Ben Messenger, who has published some further analysis.
